Original application and novmbraajia'ao, Serial No.'425,743. Divided. andthis application filed J'anuaryi28, 192s.

This invention relates to methods of coating boot and shoe parts and is herein exemplified with especial reference'to a'pplyingce In the manufacture of-shoesof the tennis type the lower portion of, the lasted upper around'the periphery ofthesho'e is coated; with a band of cement for-thepu'rpose ofsecuring a foxing strip which isrmade of'guin rubber and assists in the attachment of amtl .br sole. It is important that the vband of' cement be applied accurately in order to produce a sharply defined-line of demarcation between the coated andtheuncoated areas. If the band of cement extends above the upw 'per edge of the foxing' strip, it will deface the upper, especially if the shoes have uppers of white or light-colored material; On the other hand, if the cement does not extend fully to the upper edge of the foxing strip, this strip will not be properlysecured to the'shoeand the consequent" gaping will be detrimental, to

the appearance of the shoe and may lessen ma-= terially the lifeofthe shoe due to accidental separation between thefoxing strip and the shoe upper; l-Ieretofore the; application of cement tothe fo'x'ingxareas of'shoes has; been 1 usually effected manually, the opferative working gradually about the foxingarea witha brush'held inthe hand. This procedure,,,

- however, is obviously slow and, depending for its success upon the skill of the 0pera'tive,-is l at' best uncertain. in p 1 I One object of the invention is to providean improved method of applying cement to the foxing area of a shoe-by means of which the line of demarcation between the uncemented part of the shoe upper and the foxing area to which cement is to be applied for the attachment of a foxing strip may be accurately determined without reducing either the quantityor the quality of the-work which can be turned out. p V i In carrying out themethod of the present invention, as herein exemplified, a flexible shielding member is interposed between the cement-applying means and theshoeto define the exposed foxing area-around the lower part of the shoe to which cement is to be applied, and cementis applied to the exposed Serial No." 250,130.

'- in-illustratively described, the operator positions the shoe in a predetermined relation to p the cement-applying device, interposes a flexible imperforate shielding member between h Cement-applying device and the area- :to.

beprotected, and causes relative movement iv between the applying member and the shoeto 7 transfer the point' of application of cement around the foxing area. v

r The illustrated foxing cenientingfmachine bythe aid of whichthemethod of the presentdnvention 'mayadvantageously be prac- 'tisedcomprises a suitable frame 10 in which 3 is rotatably mounted a shaft 12,;having'fixed atone extremity-afluid applyingl member,

here shown asaf' brush 14. vThe. shaftrand; brush are rotatedffrom a convenientjsource of, power by means not shown; The brush is supplied with coating flui'd, as *cement, from a receptacle 16, through a conduit "18- passing through the frame to aicasing'li'20,-

which surrounds the upper portion of the T" brush. The flow ofcem'ent through the con duit maybe controlled'by a valve 22. Between the casing and brush, on thedoWngoing side of thelatter in its'rotation, is a gate 24 to limit the passageof cement in this direction, its relation to the periphery of f the brush being controlled by] a screw 26 threaded into the top of the casing, Be-

neath the shaft 12there'is mounted' upon frame, by-means of a screw-and-sllot connection 28- upermitting ad ustment toward and from; the, brush, a Work-restf3Q ffor' r positioning a shoe in predetermined relation to the applying member; In the present instance, sincethis is to be used in contact with the bottom of a lasted shoe to present the foxing area to the brush, theextremity 32 ofthe rest is inclined to help the operator to position this surface. of the upper properly fwith respect to the brush.

Adjacent to the applying 'surta ceof the brushisasegment'al guide member134;,'which may be formedof sheet-metal. The guiding portion properof this member, appearing" at'36, is concentric to theperiphery ofthe brush, and is U-shaped in cross sectiointhe legs of the U extending laterally otthe brush, the lower being longer and projecting beneaththeends of the brush fibers: The upper leg=of this portion 36is cut away, so that its innetextremitylies outside the edge ofthe" brush. 1 The guide member 34: sis-shown as supportedupon a bracket 88 extending from which will hereinafter appear. Carried/at one side of the frame is a bracket 44, bearingat its upper extremity fa support, .asareel'to, for a shielding strip. 48, which strip vmay. be of any suitable flexible material, paper being convenient, ill friction device 49, associated with the reel,

prevents the too free drawing-off of the strip. From the reel the strip passes downwardly and through the U-portion of the guide member, its inner edge extending beyond the loweriwall of theU andbeing held so1ne what separated from the brush and concentrictherewith. The direction in which the strip approaches the guide member is preferably-tangential, and upon the opposite side, v

'main. uncoated. Therefore, beyonddeterthe strip leaves the guide member also'in a generally tangential direction, passing up: wardly between a pair of feed-rolls 50 and n 52-rotatabletupon the frame. The roll 50, as illustrated, is. an idle bedroll, it-being flanged to prevent lateral movement of the strip out of engagement withjits surfaee The roll 52 may have extending about it cir-jiacumferential corrugations 58, which reduce the area; contacting with the stripsurfac carrying a certain amount of cement. The roll 52 is secured-upon one end of a shaft 5a journaledin the frame of the machine, and having at its opposite extremity a ratchetwheel 56. With the teeth of this wheel cooperates a pawl 58, pivoted upon a lever 60. arranged to swing upon the end of the shaft 7 5a.? Articulated to the lower end of the lever is an eccentr c rod 62, the strap of whichsurrounds an eccentric 64; fast-upon the shaft 12. It will be seen that for each complete rota-s tion of the brush-shaft 12, the eccentric may 5 be caused to move the pawl 58. through the length of one or more of the ratchet teeth, as 7 may be desired, thus through the contact of theroll 52 of the strip, advancing the latter I to'draw off from the reel 46 and present to the applying-brush fresh portions of the strip. i a V i In using the machine for cementing tennis shoe uppers, such asshown at S in Fig. 2 of the drawingsjthelasted shoe i's presented to the brush by the operator, being guided-over and positioned predetermined relation to the applying brush by the inclined end 32 of the work-rest. In preparation VfQI,l l 1lS, tl18 guide memberf a has been adjustedb'y means ofits' bolt 40 transversely of the brush to interpose ashield between the brush and the shoe, the shielding-member or strip 48 entirely covering. such a portion of the apply-- ing surface of the brush that the distance 7 between-the inner edge, of said strip and the opposite side of the brush substantially equals the width ofjthe surface to be coated. V

r The operator, holding-the work in the hands,

turns it to bring the entire length of the foxring] area into contact. with the brush, the

flexible strip extending substantially fiatwise transversely of the upper of theshoe with one edge-of the strip coinciding 'ap' proximately with the line along which. the

toxingiis to lieland defining the line of de marcation'betweencoatedanduncoated sur-,

faces.= It will be apparent that cement is applied across the edge of the strip bothtolthe :outer surface of the strip and to the foxinga'rea The portion of-thebrushbeyo'nd this line: restsupon the strip, as'the edge .or the latter projecting from the guide is flexed'and carried' toward it by the pressure of the work,

said strip thus tending .to hugthe lupper of the shoeand entirely shielding'from the Gementthe-surface of the upper whichis toremining that in the advance 'of'the shoe the the application of one part of apiece of work f tothe'brush and the'next, thefeed ofthe strip: by the roll 52 shifts the shield-strip, so that the surface which has been incontact with the brush is carried awayfrom the point of application of the work for disposal, and af fresh unsmeared section brought into action. 7

The usedportionof the strip may be cleansed in some appropriate way, and returned to the reel to beused. again, or may be thrown away,

it being so slowly advanced that relatively, little is used for; shielding a number of'the I shoe uppersoperated upon. 1

Havingdescribedvmy lnvention, what I claim as new and. desire to secure by Letters Patentofthe United States is: j

1. The method of apply ng cement to the foxing area'of a shoe which 'consists in interposing an imperforate flexible shielding definedon the shoe at the edge ofthe foxing member between a cement applying device and a predetermined portion of the upper of a shoe to define the exposed foxing area around the lower part of the shoe to which cement is to be applied, flexing the edge'of adjacent to the shielded area, and causing relative movement between the apply-ingdearea.

In'testimony whereof I have signed my name to thi said shielding member to cause it to hug the j i shoe, applying cement to said-exposed area vice and the shoe to transfer the point'of application of the cement around the foxing area.

2. The foxing area of a shoe which consists in interposing anv imperforate, shielding strip between a cement applying device and a predetermined portion of the upper of a shoe to define theexposed foxing area around the lower part of the shoe to which cement is to 'be applied, applying cement tosaid exposed area adjacent to the shielded area,"causing rela method of applyingcement to'the tive movement between the applying device and the shoe to transfer the'point of application of the cement around the foxing area, I and moving the shielding strip to present a fresh surface to the shoe so that theus'ed por tion of the shielding strip may be cleansed or renewed. I I a 3; That method of applying cement to the vfoxingarea of a shoe which consists in bringing an applying device, an imperforate shielding device and'a shoe support into cooperative spaced relation whereby the 'shielding device will protect the portion of theup' per'of a shoe lying above the foxing area from the application of cement, positioning a shoe in operative relation to said support,

shielding device and cement'applying device with the shielding device lying at a small angle against the shoe, andcausing relative movement of the shoe and theapplying device without disturbing the spaced relation of the shoe support and the shielding device to apply cement both to the outer side of said shielding device and to thefunshielded foxing area whereby a sharply defined line of demarcation between the coated and um an imperforate flexible member-lying flat- 7 Wise against the upper to prevent the application of cement 'to said shielded portion,

which is characterized by causing a relative movement of translation between an applying device and theshielded shoe to coat the whole vertical extent of each successive portion of the foxing area at any part of the shoe which is brought into cooperative relation with the applying device by applying a stripe of cement which is vwider than said foxing area so that it overlaps the flexible shielding member and is therehyaccurately i s specification.
